Can anyone clarify which drop tanks were used by the Spitfires Vs of the Ibsley Wing in the summer and autumn of 1943, 45 gallon slipper tanks, or possibly the larger 90 gallon version?

A similar question concerns 111 Squadron in the Mediterranean earlier in 1943. I understand that they were using 90 gallon tanks by the late summer, but is it known when they first received these, and whether they used other drop tanks?
